Animal concepts used in the livery extend into Frontier's marketing as well. Each animal has a specific name.[87] Animal aircraft used in their radio and television commercials include Jack the rabbit, Grizwald the bear, Foxy the fox (for whom Jack has a crush), Flip the dolphin (who always gets stuck going to Chicago rather than the warmer climates the others are going to), Larry the lynx, Hector the sea otter, and Sal the cougar. New additions are Penguins Jim, Joe, Jay, and Gary, a barbershop-style quartet, singing the praises of EarlyReturns to an audience of Frontier's well-known characters from the "a whole different animal" campaign, Hector the otter, advertising Frontier's expanding service to Mexico, and Polly the Parrot, who won the new animal audition in 2012.
Frontier offers great services and even better prices! They have a point system when you book with them, meaning eventually you can earn enough points to earn some discounted or free flights. They offer inflight entertainment and usually offer the lowest price. You get great service from the friendly staff and the aircrafts are fairly new and comfortable.
Allegiant Air (G4) is an American low-cost carrier that is headquartered in a suburb of Las Vegas. Founded in 1997, the airline does not use hubs, but has designated more than 10 focus cities. These include McCarran International Airport (LAS), Fort Lauderdale–Hollywood International Airport (FLL), Los Angeles International Airport (LAX) and Orlando Sanford International Airport (SFB). Although Allegiant flies into some major airports, many of its destinations are smaller cities or secondary airports that serve larger cities. In total, the airline serves about 105 domestic destinations in 41 states. The airline's fleet of 81 aircraft are each configured with a single Economy Class cabin.

In December 2006, jetBlue, as part of their RTP plan, removed a row of seats from their A320s to lighten the aircraft by 904 lb (410 kg) and reduce the cabin crew size from four to three (per FAA regulation requiring one flight attendant per 50 seats), thus offsetting the lost revenue from the removal of seats, and further lightening the aircraft, resulting in less fuel burned.[16]

Frontier Airlines was incorporated on February 8, 1994, by a group that included executives of the original incarnation of Frontier Airlines in response to the void left by Continental Airlines' 1993 shutdown of its Denver (Stapleton) hub.[17] Scheduled flights began five months later in July 1994 using Boeing 737-200 jetliners on routes between Denver and four destinations in North Dakota: Bismarck, Minot, Fargo and Grand Forks. By January 1995, Frontier had expanded its route network from Denver and was serving Albuquerque, New Mexico; Billings, Montana; Bismarck, N.D.; Bozeman, Montana; El Paso, Texas; Fargo, N.D.; Great Falls, Montana; Las Vegas, Nevada; Missoula, Montana; Omaha, Nebraska; and Tucson, Arizona with 737's.[18] Like the original airline of the same name, the new Frontier operated a hub at Denver (DEN) and for the first nine years used the slogan "The Spirit of the West" which was displayed above the windows and just behind the cursive letters "Frontier" on the fuselage of their aircraft. In 1999, Frontier signed agreements to begin purchasing and leasing Airbus A318 and A319 jet aircraft and had also added Boeing 737-300 jetliners to its fleet as well. Also by September 1999, the airline was serving destinations from coast to coast in the U.S., having expanded its route network to include Atlanta (ATL); Baltimore (BWI); Bloomington/Normal, Illinois (BMI); Boston (BOS); Chicago (MDW, Midway Airport); Dallas/Fort Worth (DFW); Phoenix (PHX); Los Angeles (LAX); Minneapolis/St. Paul (MSP); New York City (LGA, LaGuardia Airport); Orlando (MCO); Portland, Oregon (PDX); Salt Lake City (SLC); San Diego (SAN); San Francisco (SFO); and Seattle (SEA), all served from its Denver hub.[19]

jetBlue's first major advertising campaign incorporated phrases like "Unbelievable" and "We like you, too". Full-page newspaper advertisements boasted low fares, new aircraft, leather seats, spacious legroom, and a customer-service-oriented staff committed to "bringing humanity back to air travel".[92] With a goal of raising the bar for in-flight experience, jetBlue became the first airline to offer all passengers personalized in-flight entertainment. In April 2000, flat-screen monitors installed in every seatback allow customers live access to over 20 DirecTV channels at no additional cost.[93]

In July 2013, Frontier started service from New Castle Airport near Wilmington, Delaware to five destinations,[41] which Frontier markets as Wilmington/Philadelphia. Again, this airport had no commercial service prior to Frontier's entry.[citation needed] New Castle Airport lies roughly 30 miles southwest of Philadelphia International Airport and 75 miles northeast of Baltimore–Washington International Airport.[citation needed]
On June 22, 2009, Frontier Airlines announced that pending bankruptcy court approval, Republic Airways Holdings, the Indianapolis-based parent company of Republic Airlines, would acquire all assets of Frontier Airlines for the amount of $108 million. Thus, Frontier Airlines would become a wholly owned subsidiary of Republic.[26] However, 5 weeks later on July 30, Dallas-based Southwest Airlines announced that it would be making a competing bid of $113.6 million for Frontier with intentions to also operate Frontier as a wholly owned subsidiary, but that it would gradually fold Frontier resources into current Southwest operating assets.[citation needed]
In April 2010, Allegiant purchased six Boeing 757-200 aircraft from Thomson Airways for flights to Hawaii with the delivery of the first two in the following months. In September 2011, Allegiant Air introduced the 757 into service from their main hub in Las Vegas. Allegiant later began using the ETOPS configured 757s for service to Hawaii.[70] Fresno and Las Vegas were the inaugural destinations with nonstop service to Honolulu, Hawaii. Nonstop service to Honolulu was then added from Bellingham, Boise, Eugene, Phoenix (via Mesa Gateway Airport), Santa Maria, Spokane and Stockton.[71] Nonstop service to Hawaii was also planned from Monterey, CA but was not actually operated. Allegiant then began to reduce its Hawaii service after determining that the extensive and costly maintenance check - which happens about every six years and costs upwards of $1 million - would not be efficient on the aircraft they flew to Hawaii.[72]
In late 2009 Republic began to consolidate administrative positions and moved 140 jobs from the Frontier Airlines Denver headquarters to Indianapolis, Indiana.[29] Shortly after that, in January 2010, Republic Airways announced that it would move all of its executives to Indianapolis.[30] In February the Denver Business Journal stated that the headquarters would be moved "soon".[31] Despite this, according to the Denver Business Journal, Frontier Airlines will still maintain a local headquarters in Denver to house Training, Marketing, Customer Reservations, and Scheduling & Planning teams after extending its lease on the building through 2020.[citation needed]
Allegiant also transports firefighters for the United States Forest Service as well as college basketball teams.[44] Allegiant had a contract to supply charter flights from Miami to four cities in Cuba beginning June 2009. One aircraft was committed to the contract.[44] The contract was for fixed-fee flying, meaning all the airline was required to do was provide the dry aircraft and the flight crew. The contractor was responsible for all other costs including fuel. However, Allegiant ended this service in August 2009.[47]

Buyer beware! Do not use this service! I booked a trip for my son and then needed to change the reservation the next day. The customer service person said to cancel the first trip and "re book the whole reservation again (my son needed to stay 2 extra days). A partial refund came in 2 days later for the cost of the hotel. The refund was short $500.00 for the airfare. I called after about 6 days and was told it was being processed and would take up to 7 days. I called 5 days later (day 11) and was told it was processed and the hold up was on the part of my bank. I called the bank who had no record of this at all. They are now disputing the charges with Travelocity. It's been a time consuming and aggravating nightmare. Be aware and careful before you use Travelocity. In looking at their reviews this is not an isolated instance. They seem to have very poor business practices throughout!

I had to make some last minute travel changes and needed to SUBTRACT 2 days from my 9 day car rental reservation. The customer service agent refused to get me to her supervisor after I asked her multiple times because she was trying to charge me more money to take two days off my rental!!! Finally she told me she found something for $205 (my original rental was $268). I said, now that makes more sense. It's the same car? She said yes, I said lets make the change. Then AFTER she completed the transaction she told me that she hadn't added any of the taxes and fees so my new total is $277! Ten dollars more for two days less!! I told her that she mislead me and that she should be ashamed of herself and the company should be ashamed of itself. Obviously it doesn't care about the slew of ONE STAR reviews it has because it's not making any changes to help their customers!

jetBlue also utilizes various forms of advertising media. They use print, online, and television ads as well as advertisements on popular social media sites including Hulu and YouTube. jetBlue emphasizes a secondary slogan, "If you wouldn't take it on the ground, don't take it in the air" poking fun at competitors with hidden fees, little, or no amenities and what jetBlue considers an unacceptable level of customer service.[97]

jetBlue's founders had set out to call the airline "Taxi" and therefore have a yellow livery to associate the airline with New York. The idea was dropped, however, for several reasons: the negative connotation behind New York City taxis; the ambiguity of the word taxi with regard to air traffic control; and threats from investor JP Morgan to pull its share ($20 million of the total $128 million) of the airline's initial funding unless the name was changed.[13]

The airport director in Worcester, Massachusetts, felt that Allegiant reneged on a commitment to serve the airport for five years given the use of federal grants to assist its startup. However, the airline responded that the market was immediately unprofitable and starting service there was a poor decision; flights were reported to be 80% full.[51] Allegiant's flights average 90% full.[42]
In February 2015, Frontier announced that they will begin service to several destinations from Atlanta adding the airport as a focus city. In July, Frontier also began decreasing service from Washington Dulles International Airport removing the airport as a focus city. In early 2016 Frontier announced major route expansion from airports nationwide including Atlanta, Chicago, Cincinnati, Cleveland, Orlando, and Philadelphia.[55] In June 2016, Frontier re-established service to Port Columbus International Airport.[56] In May 2017, the airline announced opening a new crew base in Las Vegas in the fall 2017 to improve operational reliability and potentially create new jobs in Las Vegas.[57] In December 2017, Frontier began service to Buffalo, New York, with service to Denver, Colorado, and Florida, including Miami, Fort Myers, Orlando, and Tampa.[58]
In August 2017, Allegiant announced a new base would be established at the Indianapolis International Airport. The base began operations in early 2018. In February 2018, Allegiant also announced a new base would be established at the Destin–Fort Walton Beach Airport. In June 2018, Allegiant added another base at McGhee Tyson Airport in Knoxville, Tennessee. In January 2019, Allegiant announced they would be adding another base at Gerald R. Ford International Airport in Grand Rapids, Michigan.
In July 2017, Frontier announced 21 new cities and 84 new routes. These cities include Buffalo, Charleston, S.C., Pensacola, Jackson Hole, Palm Springs, San Jose, Reno, Little Rock, and Tulsa. Destinations that saw a significant bump-up in new service include Austin, Cincinnati, Long Island/Islip, N.Y., Miami, Orlando, Providence, San Antonio, and Tampa.[68]
Allegiant also transports firefighters for the United States Forest Service as well as college basketball teams.[44] Allegiant had a contract to supply charter flights from Miami to four cities in Cuba beginning June 2009. One aircraft was committed to the contract.[44] The contract was for fixed-fee flying, meaning all the airline was required to do was provide the dry aircraft and the flight crew.

In late 2009 Republic began to consolidate administrative positions and moved 140 jobs from the Frontier Airlines Denver headquarters to Indianapolis, Indiana.[29] Shortly after that, in January 2010, Republic Airways announced that it would move all of its executives to Indianapolis.[30] In February the Denver Business Journal stated that the headquarters would be moved "soon".[31] Despite this, according to the Denver Business Journal, Frontier Airlines will still maintain a local headquarters in Denver to house Training, Marketing, Customer Reservations, and Scheduling & Planning teams after extending its lease on the building through 2020.[citation needed]
Allegiant also earns commissions by offering hotel rooms, car rentals and admission to tourist attractions on its website. It sells package vacations under the brand name Allegiant Vacations. The company has arrangements with 34 hotels in Las Vegas and 21 in the Orlando and Daytona Beach, Florida, areas. In 2008, the airline sold 400,000 hotel room nights.[42] Commissions on hotel and rental car packages are up to one-third of the airline's revenue.[40][42]

In the fall of 2001, Allegiant exited bankruptcy and the case was officially closed in early 2002.[14] In March 2002, Allegiant entered into a long-term contract with Harrah's to provide charter services to its casinos in Laughlin and Reno, Nevada.[15] At the same time, the airline acquired its first McDonnell Douglas MD-80 jetliner. From 2002 through 2004, the airline developed its scheduled-service business model. By 2004, Allegiant was flying from 13 small cities to Las Vegas offering bundled air and hotel packages.
